Guys who grunt so loud you think a baby is going to drop out their bum. Seriously, do you need to do that?

People who can't stop looking at themselves in the mirror.

When you and your workout partner are using a machine, and someone asks if they can work in with you. Seriously? 3 people on a machine? You can't be serious...

People who work out in their club clothes...

Guys in the sauna who think it's hot to get it on at the gym (I avoid the sauna completely so I don't have to deal with this).

Guys who sit their naked ass down on the benches in the locker room. Can you please put down a freakin' towl before you sit your hairy ass down on a public locker room bench??? GROSS!!! Remember, we all have to sit there too...

1) Queeny guys who just talk, talk, and talk with everyone, even when they clearly see the iPod ear-set in the ears.

2) Slutty gay men who use the sauna/steamroom aside from the legitimate purposes of what its meant for, and leave their "extra manliness" behind. Apparently consideration for others doesn't exist in their book.

3) Re-rack the weights!

4) Morons who spend three-fourths of their gym time on the cell-phone, gabbing away with whoever, while occupying a weight machine/area. Assholes!!

5) Gay guys who think the gym is their catwalk. THANK goodness I go to predominantly straight gym!

1) Singing out loud to the iPod while using the treadmill/elliptical/stationary bike. If you can hold the notes in "And I Am Telling You" loud enough for me to have to hear it, then you're cardio routine ain't intense enough.

2) Is okay to fill a bit of the water bottle at the foutain, but don't fill the whole liter while a line of people are about to die of dehydration.

- People who 'bicep curl' or 'upright row' in the squat rack. It's for squatting, and/or deadlifting, and can be sufficient for weightlifting movements (power clean / etc) , though , use dumbells or pre-set barbells, or an ez-bar in the freeweight section, to perform your bicep curls.

- People who exercise in front of the dumbell racks. This has already been mentioned, but it's infuriating. Especially when you're carrying very heavy dumbells, and are quite fatigued after lifting them for a number of sets - Get the f..k out of the way you morons!

- People who sit on a machine, only to chat with their old mate for 30 minutes. If you're not using it. Get off it.

- People who use the power-rack for stretching purposes. It is not a stretching machine. There are stretching area's and other objects you can use to stretch your muscles....!

- High / Excessive grunters and talkers. I don't mind people grunting to a point, though there is a clear limit from when it is normal and natural , to when it is excessive and disruptive. Some people grunt awfully loud, others shriek like a banshee. There are some people who, even though their friend is standing right next to them, will "TALK REALLY LOUD SO EVERYONE CAN HEAR" ... and it's those people who need their voice boxes damaged.

After an intense cardio workout, you get the runner's bubblies (aka number 2), do your thing, and then because your butt was so sweaty the seat cover sticks to your rear and you have to pry off the damn thing piece by piece >_<

Guys who carry ALL their belongings from their locker to the shower cubicle and get changed in there... really, if you're that paranoid someone might see your weiner (heaven forbid), surely you should get changed at home?

Guys who leave a trail of belongings (towels, shirts, water bottles, syringes...) at each station they did a set at. Don't f*****g tell me you're only going to be a minute and so you don't want to share a bench!

The sweatiness thing has been mentioned, but needs repeating

Those twazzocks that do 3 curls and then check out their arms in the mirror- what the hell is that about?!?!

Carrying on a conversation with some tosser on the other side of the gym floor. We don't all need to hear how you scored last night...

Creepy lurkers in the change rooms

Twits who strew belongings all over a bench so they don't have to sit next to someone as they change

i just cannot for the life of me understand people that don't put the weights away. it makes me so indignant. nothing is more frustrating to me than patrolling the entire gym for that one other 20 pound dumbbell that someone left in some remote corner.

1: People who complain about how much I sweat. I clean it up when I'm finished, so shut up. When people work hard, they sweat. It's a gym, after all.

2: Mouth breathers on cardio equipment who have a mouthful of rotten teeth. I can stand armpit odors. I can't stand that smell. I also can't stand foot odor. If your shoes need to be replaced because YOU can smell them, chances are that I can also smell them.

3: People who use the sophisticated cardio machines to do the least sophisticated programs possible, such as the manual setting.

4: Guys who don't bring water with them to the gym. I hate going to get on a machine only to find that some doofus is taking ninety second trips to the water fountain in between sets. How am I supposed to know that he's using a machine? Lots of guys at my gym do this and then talk to you like you're an idiot for taking over the equipment they were using.

1) People hogging the equipment. Especially the ones who just sat on it and socialized. (Especially the "senior citizens" using the area as a social club, since they weren't even paying for it.) I had 30 minutes, tops, to get in and get out. Some of those people never budged (or exercised) during that time.

2) Loud people. There were always two or three people who not only talked incessantly about the most trivial and moronic stuff, but always did so at full volume. When they were in there, there was no hope of thinking or listening to music.

Finally I realized that there was very little at the gym that I couldn't get cheaper and better with a home gym. If things really get on your nerves that much, just walk away.

Not racking the weights, particularly dumbbells (I am not your maid, nor should I have to look all across the gym for where someone decided to hide the set of 25 pound dumbbells)

Racking the weights stupidly (When a bench station has 8 different pegs for plates, you shouldn't be stacking different weight plates on the same peg. It's annoying to have to shift a couple of 45 pound plates when I'm trying to get to one of the 5 pounders.)

Sitting on a machine for more than 30 seconds without using it (If it's a weight stack machine and you want to rest a minute or two between your sets, let someone else work in, as it takes about 2 seconds to change the weight. I'm more sympathetic when it's a machine where you put on plates.)

People claiming way too much equipment at once (When the gym's busy, you get either 1 machine, or a bench and either one set of dumbbells or one barbell at any given time. If the gym isn't busy, that's another matter, but when there are lines it's just rude to claim 4 sets of dumbbells or 3 machines or whatever, and I will ignore your claim.)

I will admit to doing some things which apparently infuriate others, though. I use the fancy treadmill on the manual setting. I pick that type because a) it's longer than the really cheap ones and I have a long stride, and b) it has fans built into it--and I don't really care if someone else wants to use advanced hillclimber program you can set that one to and has to wait for it, I feel I have as much right to that piece of equipment as they do. I don't bring water to the gym, but I also don't take a water break between sets on a machine, but rather wait to take my water break between machines. And I do look in the mirror when doing certain exercises, because I want to see if I'm maintaining proper form.
